绘制扭矩与角度的关系图是描述旋转开关触觉特性的通用标准。这种图形化描述源于现有的测量技术：扭矩和位置传感器的可用性。然而，由于它不能描述直观的感知特征，所以没有考虑人的感知。因此，大多数人，除了那些有很多经验的人，都无法创造出对扭矩特性的逼真的触觉解释。这个研究项目应该回答的问题是：旋转开关的使用者直观地感受到什么反馈？以前我们用不同的方法来描述触觉特征。我们发现了一个主要假设，即绘制的耗尽能量对角度的描述比绘制的扭矩对角度的描述更直观地表示。我们提出了另外四个假设来检验这一主要假设。它们是正弦和三角形形状的静止位置、相似度和幅度以及形状的不对称性。为了评估这些假设，我们对受试者进行了测试。我们使用旋转触觉模拟器，通过它可以改变所需的参数。整个测试自动运行，受试者自己控制单次测试的持续时间。两个基本原理被用于测试：在第一种情况下，比较两种触觉特征。应用的方法是在特征相等的情况下对问题的是非答案进行解释。在第二种情况下，受试者的任务是将触觉分配给图形表示之一。研究人员对25名受试者进行了80次单次测试，结果证实了这些假设。可以发现明确的趋势，可以在每一项测试中证实假设，而不存在任何矛盾。这项测试还被设计用来回答在与旋转开关的连接中触觉辨别的刚刚明显的差异。此外，还可以表明，仅显著的差异与扭矩特性的形状无关。旋转开关的触觉(可下载PDF)。可从：https://www.researchgate.net/publication/228812226_Haptical_feeling_of_rotary_switches[2016年4月2日访问]。
It is a general standard in the description of the haptical charac-terization of rotary switches to plot the torque vs. angle. This graphical description is originated in the available measurement technology: the availability of torque and position sensors. However, it does not consider the human perception as it cannot describe the intuitively perceived characteristics. Therefore most people, except those with a lot of experience, are not able to create a realistic haptical interpretation of the torque-characteristic. The question that should be answered by this research project is: what feedback does the user of a rotary switch feel intuitively? Previously we used different ways in order to describe the haptical characteristic. We found a main hypothesis that the description of the used up energy plotted vs. angle shows a much better intuitive representation than the description of plot-ted torque vs. angle. We stated four additional hypotheses to test this main hypothesis. These are the rest position, the similarity and the amplitude of sinusoidal and triangular shape and the asymmetry of shapes. In order to evaluate these hypotheses, tests with subjects are made. We use a rotary haptical simulator, by which the re-quested parameters can be changed. The whole test runs auto-matically and the subject controls the duration of the single tests by himself. Two basic principles are used for the tests: In the first case two haptical characteristics are compared. The applied method is the interpretation of the yes-no answers to the question if the characteristics are equal. In the second case the subjects have the task to assign the haptical feeling to one of the graphic represen-tations. The hypotheses are confirmed with 25 subjects on 80 single tests each. Clear tendencies can be found that confirm the hypothesis in each test without any contradiction. The test is also designed to give answers about the just noticeable difference of haptical discrimination in connec-tion with rotary switches. Furthermore it can be shown that the just noticeable difference is independent of the shape of the torque characteristics. Haptical feeling of rotary switches (PDF Download Available).
